Floating like a balloon and as blue as the sapphire safely nestled in its side, the Ballon Bleu stainless steel and leather <b>watch</b> by <b>Cartier</b> is guaranteed to add a dash of elegance. Roman numerals are guided on their path by a sapphire cabochon winding mechanism guarded by an arc of precious metal. The convex curves of the case, guilloché dial, sword-shaped hands, and bracelet links ensure the Ballon Bleu watch excels within the world of Cartier watchmaking. <b>Each Cartier creation is available to order online using our Click & Collect service at Selfridges London. You will collect your order, presented in the iconic red box, at the Cartier boutique in The Wonder Room. &nbsp;&nbsp;</b>
